26 • SLASH 4x4
ADVANCED TUNING ADJUSTMENTS
CAMBER GAIN
Slash 4x4 has provisions for adjusting the camber gain geometry of the
front and rear suspension. "Camber gain" refers to an increase in camber
angle as the suspension is compressed. The camber gain of the vehicle
can be changed by moving the camber link attachment to a different
horizontal mounting position. Adjusting the camber gain will alter the tire
contact patch as the suspension is compressed. Making the camber link
shorter will increase the camber gain. This makes the vehicle more stable
over bumps, but reduces traction on smooth surfaces. Lengthening the
camber links has the opposite effect.
• Front Camber Gain
To increase the camber gain on the front
suspension, move the inner camber link
ends out to Position 3. Position 4 is the
stock setting.
• Rear Camber Gain
To increase the camber gain on the rear
suspension, move the inner camber link
ends out to a different attachment hole
(Position 1 or 2 in the image. Position 3 is
the stock setting).
Once you make adjustments to the camber
gain, you may need to re-adjust the static camber to suit
your tuning needs.
ROLL CENTER
Slash 4x4 has provisions for adjusting the roll center geometry of the
front and rear suspension. Roll center refers to the virtual axis around
which the chassis will roll when subjected to cornering forces. The roll
center of the vehicle can be raised by mounting the inner ends of the
camber links in a lower position. Raising the roll center will effectively
increase the roll stiffness of the vehicle (similar to installing swaybars).
Adding roll resistance to one end of the vehicle will tend to add traction
to the opposite end. For example, increasing roll resistance in the rear will
provide more traction for the front wheels and potentially more steering.
Raising the roll center on the front and rear equally will increase overall
roll resistance without changing the handling balance. The default factory
locations are designed to make the truck easier and more forgiving to
drive and less likely to traction roll in turns.
• Front Roll Center
To lower the roll center
on the front suspension,
move the inner camber
link ends up to a different
attachment hole (Position
1 or 2. Position 4 is the stock setting). To lower the roll center further, move
the outer camber link ends to the lower position on the C-hub.
Bump steer correction - "Bump steer" refers to
unwanted steering inputs caused by suspension
Front
movement. Slash 4X4's suspension geometry is
designed to minimize bump steer. If you are using
the upper hole on the C-hub (image A) and either
of the two lower holes on the shock
tower (positions 3 or 4 in "Front"
image), the tie rod ball should be
oriented with the large flat end on
Rear
top (stock position - image B). When
using any other combination of camber
link attachment points, the tie rod ball
should be oriented with the large flat end
on the bottom (C).
• Rear Roll Center
To raise the roll center on the rear
suspension, relocate the inner camber links to one of the two holes
(position 4 or 5 in image) in the lower row of the rear camber link
attachment, located near the base of the rear shock tower.
Once you make adjustments to the roll center, you may need to re-adjust
the static camber to suit your tuning needs.
